# --description--

Character classes also allow you to indicate a range of characters to match. You need to specify the starting and the ending characters separated by an hyphen, `-`. Characters follow the Unicode order.

Modify your `pattern` variable to match any letter `t` preceded by a lowercase letter in the `quote` variable. Use the range of characters from `a` to `z` for that.

# --hints--

You should modify your `pattern` variable to match any letter `t` in `quote` preceded by a lowercase letter using the `[a-z]` class.

```js
({ test: () => assert.equal(__userGlobals.get("pattern"), "[a-z]t") })
```

```py
import re
import secrets
import string


def generate_password(length, nums, special_chars, uppercase, lowercase):
    # Define the possible characters for the password
    letters = string.ascii_letters
    digits = string.digits
    symbols = string.punctuation

    # Combine all characters
    all_characters = letters + digits + symbols

    while True:
        password = ''
        # Generate password
        for _ in range(length):
            password += secrets.choice(all_characters)

        constraints = [
            (nums, '[0123456789]')
        ]        

    return password

# new_password = generate_password(8)
# print(new_password)
